The MicroRDS Encoder is a professional
full-featured FM broadcast RDS encoder module that supports basic RDS services at
unmatched acquisition costs. It provides all common RDS services: Program service name,
dynamic PS, Radiotext, Program Type identification, Traffic Program, Traffic Announcement
and Music/Speech flags, Alternative Frequencies list and some more. This unit is ideal for
embedding into existing FM transmitter as well as for development and hobby purposes.
Direct digital synthesis of the RDS signal, equipped with pilot input for optional
Simple RDS encoder with basic set of features
Very small dimensions and power consumption
Easy to use
Selectable control interface (RS-232 or I2C
bus) supports various connection methods for configuration
EEPROM memory for data storage during power-off
Broadcast quality output signal
Continuous RDS transmission during all operations
Includes text features like dynamic PS, parsing and
Supports both stereo and mono transmission
documentation, production data download
RDS services directly supported:
PS (Program Service), PI (Program
Identification), PTY (Program Type), TP (Traffic
Program), TA (Traffic Announcement), DI (Decoder
Identification), M/S (Music/speech), AF (Alternative
Frequencies), RT (Radiotext), raw User Defined
Basic electronics skills are required for proper
installation of this device!
If you prefer complete plug-and-go solution rather, look at the P232.
You can order the MRDS1322 part here
in the section 'RDS Encoders - Parts'.
After install and first opening select appropriate
connection parameters on Hardware card. The software can send current song artist and title
information if your broadcast automation system provides on-air text file.
The Magic RDS 4 brings following benefits to the MRDS1322-based RDS encoders:
Common or independent control of up to 128 encoders,
direct support of connection over Ethernet,
Radiotext Plus (RT+) and real-time (CT) transmission,
External text sources with powerful text processing tools,
Task scheduler, Text conditions, SNMP, ASCII terminal emulator, encoder backup/restore,
connection bridges with virtual ports and communication protocol translation (for example from UECP).
In this configuration the RDS encoder can be
controlled by the TinyRDS or Magic RDS 4 Windows application. The basic connection is extremely simple
since the MicroRDS incorporates all hardware necessary. You only require a 5V power supply
and standard DSUB connector. The RDS signal output that can be fed directly to RDS, MPX or
SCA modulation input of your FM exciter.
